RTX Corporation has been named in a $1.8 million contract suit after being pulled into a legal battle involving a business consultant and a technology subcontractor over disputed payments and out-of-scope work on an IT project.

Delaware North America LLC, a Texas-based consulting firm, filed a third-party complaint against RTX, alleging the aerospace and defense company is responsible for project delays and unpaid work stemming from “Project Sky,” an IT initiative following RTX’s 2021 divestiture of a training technology business to Vertex Aerospace.

Delaware was engaged by RTX under a $17 million agreement to support the transition. Delaware then subcontracted Chicago-based Fission Consulting LLC for data migration services under a $1.025 million deal. According to court documents, delays attributed to RTX's contractual responsibilities—such as data extraction—forced Delaware to request additional services from Fission outside the original contract scope.

Fission is now suing Delaware for $1.8 million in unpaid invoices, while Delaware argues that RTX withheld milestone payments and pushed for extra work not covered in the original agreement. Delaware's complaint accuses RTX of attempting to extract additional work and intellectual property without proper compensation and seeks over $7 million in damages.

The litigation was originally initiated by Fission in federal court before being refiled in Connecticut Superior Court. On June 2, Judge Trial Referee Edward T. Krumeich II granted Delaware permission to bring RTX into the case. Delaware has also filed counterclaims against Fission, arguing that any liability to the subcontractor should be covered by RTX.

The consolidated cases—Fission Consulting LLC v. Delaware North America LLC (FST-CV24-6066340-S) and Delaware North America LLC v. RTX Corporation (FST-CV25-6072947-S)—are pending in the Stamford-Norwalk Judicial District of Connecticut Superior Court.
